Title: Mass spectrometry
Inventor: FUJIMOTO TAKEO
IPC: H01J49/26
Filed: 1983-06-16
Abstract: PURPOSE:To eliminate time and labor required to attach and dettach magnets, and vacuum leakage causing by the attaching and dettaching, by providing a pair of electromagnets, whose facing parts are excited to opposite plarities, in their covers made of an insulating material above and below the ion source of a mass spectrometer, and turning off the electromagnets when gaseous H2 is analysed. CONSTITUTION:Electromagnets 13 and 13' enclosed in covers 14 and 14' made of an insulating material such as glass, ceramics, etc. are provided above and below filaments 11 and a trap 12 which constitute the ion source of a mass spectrometer. Since light gases such as gaseous H2 are repelled away by rotation of thermoions flowing between the filaments 11 and the trap 12 by action of the electromagnets 13 and 13', and then an analysis becomes impossible with decrease in sensitivity of the mass spectrometer, the electromagnets 13 and 13' are turned off.

Title: Program action timing device
Inventor: NISHIWAKI YOSHITETSU
IPC: G06F21/12
Filed: 1986-05-14
Abstract: PURPOSE:To completely prevent a program from being run illegally apart from an executable period by generating an interruption signal that cannot be masked if a decoded executable period excludes the current time. CONSTITUTION:Prior to the execution of a program, an encoded executable period code recorded in the program is inputted and decoded in a decoder 11, and stored in a register 12. On the other hand, a timing device 12 transmits time to a comparator 14 without fail. The comparator 14 compares the time with the executable period stored in the register 12. If the time is included in the executable period, an interruption generation circuit 15 never generates an interruption signal. If not, the circuit 15 generates the interruption signal that cannot be masked to a computer. Accordingly the program concerned can be run only during the executable period which is encoded and recorded in the program.

IPC: G11B21/10
Filed: 1985-05-20
Abstract: PURPOSE:To prevent a generation of jittering, a variation of a reproduced output and a wear of a recording medium by changing an amplitude of a variable dither signal outputted from a variable dither signal output section proportionally to the amplitude of an error signal outputted from an error signal output section. CONSTITUTION:In proportion to an amplitude of an error signal outputted from an error signal output section 5, an amplitude of a variable dither signal outputted from a variable dither signal output section 6 is changed. A width of an oscillation of the head 1 is changed proportionally to the dislocation in the track. Accordingly, when the dislocation in the track is large, the width of the oscillation of the head 1 is enlarged and when the dislocation in the track is small, the width of the oscillation can be reduced. Thereby, the width of the oscillation of the head 1 is not enlarged above a necessity, and a generation of a jitter, a variation of a reproduced output and a wear of a recording medium or the like can be prevented.

IPC: H04N5/262
Filed: 1990-04-26
Abstract: PURPOSE:To obtain a picture with clear contour by providing a contour section detection means, an interpolation signal generating means and a selection means and selecting an inputted picture signal or an output of the interpolation signal generating means in response to an output of the contour detection means and outputting the result to an external device. CONSTITUTION:When a luminance signal subject to scanning line interpolation is inputted to an input terminal 101, the signal is inputted to a 1-line delay line 102 and to one input terminal of subtractors 104, 107. On the other hand, the output of the delay line 102 is inputted to one input terminal of a subtractor 105 and a delay line 103. A signal delayed by one line is outputted from the delay line 103 and the signal is inputted to one input terminal of the subtractor 105 and a selector 111. A picture signal inputted to the selector 111 is controlled to select an interpolation signal when the contour exists and to select an inputted picture signal when the contour does not exist based on a flag 110 representing the presence of the contour. Thus, a signal subject to contour emphasis in the vertical direction is outputted to an output terminal 112.

Title: Thyristor exciting device
Inventor: SHIMIZU TERUYOSHI
IPC: G05F1/455
Filed: 1981-07-13
Abstract: PURPOSE:To easily conduct a thyristor even with larger inductance of a load, by controlling a trigger angle of the thyristor near the phase angle setting an instantaneous value of a voltage to a maximum. CONSTITUTION:A trigger angle of a thyristor 3 is phase-shifted to the beta limit, and an exciting condition detector 10 outputs a signal a signal of the end of exciting condition after the exciting condition is matched. An initial trigger angle controller 12 gives a command to a controller 7 that the trigger angle of the thyristor 3 is gradually retarded from the beta limit to a phase angle determined with the voltage difference between the output of a current reference generator 6 and of a current detector 5. Thus, when the trigger angle changes the phase from the beta limit, the trigger pulse is given to the gate around the  trigger angle where the instantaneous value of the voltage is maximum. In this  case, since the instantaneous value of the voltage is high, a current easily flows  to an inductive load 4 and the current can quickly be risen to the holding current of the thyristor.
